A subset of the population in the United States (U.S.) are known as "super-utilizers," and they are responsible for a disproportionate amount of resource intensive healthcare and associated spending. Super-utilizers tend to have multiple co-morbidities, a term called, "multi-morbidity," and they also have other population risk factors, including low socioeconomic status, housing instability, and being uninsured. Consumer expenditures are data on purchasing habits, and as a data source, they may offer information about the risk for super-utilization of resource intensive healthcare along with risk for multi-morbidity. Despite the large burden super-utilizers place on the U.S. healthcare system, identifying them and optimizing their healthcare to reduce their utilization remains a crucial challenge. In addition, multi-morbidity is a documented risk factor for resource intensive healthcare, however, dietary recommendations among those managing multi-morbidity are limited. This dissertation seeks to address these two gaps by (1) predicting resource intensive healthcare among population units, which may address limitations associated with existing models generated among individuals and (2) using consumer spending data to study diet choice among multi-morbid households, which may identify behaviors to promote or reduce to support healthy lifestyle practices. In this dissertation, I demonstrate the utility of using machine learning to develop models for predicting resource intensive healthcare utilization and associated spending among U.S. counties and U.S. hospital service areas (HSAs) using routinely collected data from governmental and non-governmental sources, including demographics, adult and child disease characteristics, community characteristics, and consumer expenditures. The prediction model performance in this thesis matched or exceeded existing models generated at the individual level, offering an alternative method for identifying super-utilization of resource intensive healthcare and associated spending. Additional analyses identified population characteristics explaining variation in resource intensive healthcare across U.S. counties and HSAs, highlighting potential modifiable risk factors to target for health system or community interventions. To further understand how consumer expenditures related to multi-morbidity, a separate analysis used packaged food and drink purchases to study diet choice among households with multi-morbidity. Recommendations to promote healthy lifestyles among those with multi- morbidity should focus on reducing unhealthy packaged foods, especially from unhealthy items, including processed meats, and cookies.
